Memory question

What is more important system memory or gpu memory? I ask because I am deciding between two MSI gaming laptops. One has 64gb of system with 12 gb of vram, the other has 32 gb of system memory and 16gb or vram, they both have the same video card.

    Not sure about gpu memory verses ram memory.  I know low ram memory makes computer run slower.  Or at least that is what I assume makes my computer slow.

    well, the one with the 64GB ram is now sold out. I would wait but my current computer keeps having issues.

    GPU memory (VRAM) is essential for rendering. If the scene exceeds the available VRAM it will do fallback to CPU.

    I would look into if the one with 16 GB VRAM can be upgraded to more RAM. Usual guide is to have 3 times more RAM than VRAM. If not it might take longer time to prepare the scene, as the computer will use virtual RAM (desk) for handling the loading.

    I doubt it can, but if I follow, you're saying that 64gb ram with 12 GB beam might be better overall since the other will have cream at only twice the system memory? I currently have a 32 GB with 8gh of ram and that is fine. The 64 GB is a few hundred more than the other.

    I had a machine with 6Gb Vram & 16Gb Ram. It worked quite a lot better with 24Gb RAM. But the low Vram was a big issue.

    It's cheaper to increase Ram later than change the GPU. I'd go for Vram and try to upgrade the Ram later.

     I would go with the 32GB system memory 16GB GPU memory. 
     Just a reminder, RTX 5000 series GPUs will not work with Daz Studio 4.xx, but are supported in Daz Studio 2025 Alpha.

    THis I did not know and both the ones I am looking at are geoforce rtx 5070, Dang.

    will rtx 4000 series work?

    Yes, RTX 4000 series will render in IRay. I would prioritize the VRAM.

    RTX 4000 GPUs are good to go on Daz Studio 4.xx.  Rather overpriced currently IMHO.

  • ChoppskiChoppski Posts: 627

    Oy, all the ones I want are rtx5000. Does that mean that the new daz studio doesn't use iray? WIll all my lighting and materials not work? 

    I was also hoping for a 2tb hard drive but those only come with the higher end video card (for reasons I don't understand). 

    Basically, what I am seeing with the 4000 series are computers with the same hard drive storage, same system memory (32 gb) and same vram (8gb) that I have now. I know the processors would be faster, but you have to use windows 11 which, from what I have seen and read, is a hard drive memory hog. 

    How stable is DS2025? The ALpha part worries me. 

  • dtrscbrutaldtrscbrutal Posts: 566

     It is still Iray, just a newer version that does not work in DS 4.XX. I have not used the DS 2025 Alpha, but there are multiple threads in the Daz Studio Discussion forum. I am sure someone more knowledgeable than I can answer your questions there.

    The Alpha was released early because of the RTX 5000 series kept folks from using DS 4.24. It is the qt4 vs qt6 issue. So right now plugins and most scripts do not work in DS2025. But on my MacMini M4 the other day I was able to create a render of a character, outfit, hair, scene, and simulate it. I had to replace the hair as it had an unusual reaction to dForce. The new hair was close to 6 million vertices and it crashed. I had saved thankfully prior to that. Rebooted and reopened and loaded the hair again. I also used PowerPose. Rendered okay. Apple computers have access to Filament/FilaToon now as well. But if I want to use many of the scripts I rely on, I save my scene file and reopen them in the Beta, DS 4.24.

    One thing I have found out is many of my renders run faster on DS2025 than on DS 4.24.

    But if you want more technical details:

    Daz Studio 2025 (6.25.2025.x) - NVIDIA Iray 2024 - Daz 3D Forums

    Daz Studio 2025 ALPHA - version 6.25.2025.22607! (Updated August 14, 2025) - Daz 3D Forums

    So, I found out some things. the computers I am looking at do have expandable memory. Not cheap, but possible. I am thinking about one that has a 4070 card with 12gb vram, but the system only has 32 gb of Ram. Would that function ok? I mean I can eventually upgrade the system ram to 64, if not. However, yes, this computer is about the same as the one that had the 5070 card, 32gd of ram and 12 gb video card. So the video card overpriced? maybe.

    But would the 32gb and 12 gb be ok together for rendering?

  • 3DSaga3DSaga Posts: 641

    I think that would work fine. A freind of mine has a laptop with a 4070 and 12 gb VRAM. It performs at least as well, if not better, than my desktop with a 3080. My desktop has 32 Gb of RAM, and I haven't had any issues with it. My renders usually have an evironment, and at least 2 figures (G8 and/or G9).  I should also add that my friend's laptop also has an I9 CPU which runs rings around my I7. The laptops you're considering must have some decent CPUs to support the other components.

    Yes it would be fine - and even finer if you do upgrade to 64gb ram. 

    However, it's all but impossible to upgrade the GPU in a notebook and so you would be using a 4070 for however long you keep your machines.

    Unless you absolutely must buy now, I would wait until Daz2025 is stable and buy a 5-series gpu machine.

    If you must buy now - Still consider the 5070 (it'll allow you to upgrade ram at some point too). Then install Daz-2024 AND Daz-2025. Make scenes in Daz2024 (where all the plugins work) and render / fine tune in Daz 2025.

    Paying a lot for an older notebook (because they are difficult/impossible to upgrade components) - unless it is very CHEAP - isn't ever the best idea. (Unlike a desktop, in which you can upgrade components)

    Yes, this is exactly what I am wrestling with. I thought I had to buy a new one right away because my computer has started to get blue screens out of the blue, but I am wondering if that is mostly because of the latest update. Also, after October I will no longer have support for windows 10. However, to pay close to what I was thinking for a laptop with 5000series and only 1 tb of storage is hard to accept. I hadn't thought about starting in 24 and then fine tuning in 25. But I do tend to stay with a version until I am happy. I am only using daz 4.22 at the moment. 

    BTW does 2025 allow you to use 4000 series nvidia cards? I am assuming that you won't be required to have a 5000 plus to use daz 2025, is that correct? 

    also thanks for the feedback.

    Correct !  I don't have a 50 series card by now ~~ Rendering with my 30/40 cards in DS 2025 works as expected (most of the time ~~)
